Beach Weather Stations - Automated Sensors

Beach Weather Stations - Automated Sensors

The Chicago Park District maintains weather sensors at beaches along Chicago's Lake Michigan lakefront. These sensors generally capture the indicated measurements hourly while the sensors are in operation during the summer. During other seasons and at some other times, information from the sensors may not be available. See for a dataset with similar measurements on the lake water, itself. The sensor locations are listed at


NameSocrata field nameColumn name in sgr mountData typeDescription
HeadingheadingheadingNumberThe current heading of the wind-measurement unit. The ideal value to get the most accurate measurements is true north (0 degrees) and the unit is manually adjusted, as necessary, to keep it close to this heading
Measurement Timestamp Labelmeasurement_timestamp_labelmeasurement_timestamp_labelTextThe Last Updated value in text format, suitable for use in the Visualize function.
Station Namestation_namestation_nameText
Measurement IDmeasurement_idmeasurement_idTextA unique record ID made up of the Station Name and Measurement Timestamp.
